Data resolution is 8.3 samples per second. Plots are limited to 30 minutes of data. If you need to view a longer period of data please return to our data server for the 1 minute and 6 second data.

Time Format
All data are displayed in UTC. (Note: Prior to June 2004, this data server
used International Atomic Time (TAI) for data collected in 2000 and onward.
TAI differs from UTC
by fixed increments where a leap second occurs. On JAN 1 2000, a time in
TAI could be converted to UTC by subtracting 32 seconds. For a table of conversions from TAI to UTC, click here).

The coordinate system for these high resolution data is spacecraft coordinates with Z along the rotation axis of Polar, X along projection of sun in spin plane.
